Abstract

Since the bacterial microorganism accumulation on the teeth surface causes a biofilm called dental plaque, periodical removal is essential. In novel methods, it is done by an ultrasonic tool creating cavitation; therefore, the dental plaque will be removed from the tooth surface. The dental scaling tool geometry plays an important role in the tool nose cavitation. In this study, the dental scaling tools of one device have been investigated and analyzed by the theoretical equations. Then the natural frequency of the transducer and each of the dental scaling tools were determined by the COMSOL Limited element software and were compared with the results of the theoretical equations. Also, the natural frequency of the tools was known by the impedance analyzer. The effect of the deformation on the nose and curve was investigated by the tools deformation comparison. The dental plaque performed practically displayed a desired accordance between experimental and practical findings.
